Title: Image reader
Inventor: AKANUMA GOICHI
IPC: H04N5/372
Filed: 1998-03-06
Abstract: PROBLEM TO BE SOLVED: To provide an image reader that enhances image quality by suppressing deformation of a frame supporting integrally a light source, a read sensor and optical elements due to the heat of the light source. SOLUTION: A frame 32 made of a mold forming or the like of a close contact image sensor 31 supports a refractive index distribution type lens array 33 and a read sensor attached to a sensor board 35 is placed below the refractive index distribution type lens array 33. A light source 36 with a large heat generation amount such as a fluorescent light is supported by a side wall of the frame 32 at the outside of the frame 32, and a binding member 38 made of a material whose thermal expansion coefficient is smaller than that of the frame 32 and with a rigidity larger than that of the frame 32, e.g. an iron plate is fixed to a part of the frame 32 facing the light source 36 by screws 39. Thus, the heated side of the frame 32 expands and tends to bend due to a heat from the light source 36, but the binding member 38 suppresses the bent to enhance the image quality of a read image.

Title: Heat-accumulator for heater
Inventor: ENDOU TAKUYA
IPC: F17C3/10
Filed: 1979-06-11
Abstract: PURPOSE: To improve a heat retaining property, by filling a gas of lower thermal conductivity than air, in a heat insulating layer which encloses a heat-accumulative body to retain its heat, so that the thermal conductivity of the heat insulating layer is lowered.  
     CONSTITUTION: In a heat-accumulator 1 for a heater, heat is stored in a heat-accumulative body 4 which is enclosed with a heat insulating layer 6 filled with a heat insulator 5 to retain the heat. This heat is used as a heat source. Gas such as "Freon 12 or 21 ", carbon dioxide gas or the like having a lower thermal conductivity than air is filled in the heat insulating layer 6 instead of air to heighten the heat retaining property of the layer. Therefore, the thickness of the heat insulating layer 6 can be greatly reduced. This results in making the heat-accumulator compact as a whole. The operating time of the heater can be lengthened even if a material of low heat-accumulation density is used.
